Opinions?

Would love if you fine people could give your opinions on what could be going on here. These bronze patches seem to be mainly starting at buds and aren't brittle or dry. Could this be a boron deficiency?

Looks like light burn

Growing under a 320w qb that is 20 inch from top of plant. Would bleaching happen before burn? Im not seeing any

Seeing as it’s the top cola that has the burn I’d think it’s probably from the light, you might want to raise it a few inches just to be safe. 20” is about as low as you’d want to go with 320w

Put to 2ft and unfortunately that is maxed out. Dropped to 75% and will go lower if I see it spreading

Light bleaching,
